Four-year outcomes of a single-center experience with coronary everolimus-eluting bioresorbable scaffolds.

Background: Bioresorbable scaffolds (BRS) have been introduced to overcome the limitations of drug-eluting stents and the ABSORB (Everolimus-Eluting BRS, Abbott Vascular, Santa Clara, CA, USA) was the most extensively tested. Nevertheless, major RCTs reported higher rates of target lesion failures and BRS thrombosis at 3 years follow-up, bringing to the withdrawing of the device from the market. It has been suggested that a better lesions selection and an optimized implantation technique could mitigate the displayed adverse results.

Accuracy and Repeatability of Automated Injector Versus Manual Administration of an MRI Contrast Agent-Results of a Laboratory Study.

Objective: The aim of this study was to compare flow rates over time and the deviations from the target flow rate of a magnetic resonance imaging contrast agent achieved by an automated injector versus manual injection.

Materials And Methods: In this laboratory study, the magnetic resonance contrast agent gadobutrol was repeatedly injected by an injector and by 10 experienced technologists. Six scenarios with 2 different target flow rates (1 and 5 mL/s), 2 different contrast volumes (10 and 20 mL), and 2 different intravenous (IV) catheters (22 gauge and 20 gauge) were tested.

Training-induced right ventricular remodelling in pre-adolescent endurance athletes: The athlete's heart in children.

Aims: Little is known about the adaptation of the right ventricle (RV) to endurance exercise in children. The aim of this study was to assess the effects of 5months of intensive training on RV morphology and function in preadolescent endurance athletes.

Methods: Ninety-four children were evaluated in this study.

Electrocardiographic Changes Induced by Endurance Training and Pubertal Development in Male Children.

Training-induced electrocardiographic changes are common in adult athletes. However, a few data are available on electrocardiogram (ECG) in preadolescent athletes and little is known about the potential changes induced by training on 12-lead electrocardiogram (ECG) at rest. Twelve-lead ECGs at rest and complete echocardiographic examinations were performed in 94 children (57 endurance athletes, 37 sedentary controls; mean age 10.

Optical coherence tomography evidence of endothelial erosion as a cause of ST-segment elevation myocardial infarction.

High-resolution intracoronary imaging provided relevant insights into the field of pathophysiology of acute coronary syndromes (ACS). Human autopsy studies have shown that endothelial erosion may lead to intravascular thrombosis and acute myocardial infarction. We report the case of a 51-year-old woman presenting with ST-segment elevation ACS.
